` j Application led March 27, 1907. Serial No. 364,8-25.

America, and resident of La Grange, Cook county, Illinois, haveinvented'a certain new and-useful Im rovenient in Reversible En? velops,of whic 1 the following is a specification.

"fas

. velop sealed forthefirst time.

My .invention contemplates an improved reversible envelop--that is tosay, an envelop which can be torn open and turned Wronv side out, andthen reversed for a secon transmission through'the mails.

i My improved envclo i, as herein disclosed,-

s two end fla s 'whic are guinmed on the `\\i1inei' sui'facest ereof,and u per and lower flaps which are gummed a ong the inner' edgesthereof. Said up er and lower flaps are-` also scored along tieir edges,so4 that these flaps can be torn off with clean edges. After this,the'end flaps can be reversed, and the top and bottom flaps may then. bereversed and sealed by moisteniiig the mucilage on the surfaces of theend flaps. Irr this way the envelop is readily reversible and can beused a. second time for transmitting a letter through themail. i

In the acconipanyino drawings'Figure 1 shows the inner side of the blankfrom which my envelop is made. .Fim 2 shows the en- Fig. 3 shows the topand bottom flaps of the envelop torn off or disconnected, leaving narrowportions iidherinv to the outer suifaces of the envelop. Fig. 4 showsvthe enti-re envelop reversed or turned wrong. side out, the bottom flapsecured in place and the upper flap ready to be turned domi and securedin place by moistening the inueilage on the outer surfaces of the twoend flaps. A

As thus illustrated, my improved envelop blank has a middle or bodyportion A provided with end iaps a and'upper and lower or top and bottomflapsfl' and at. The end flaps are gummed at 1 2, and 3 4, on the innersurfaces thereof, as shown more clearly in Fig. l. The flaps a, a- -arescored at 5-6-7 and 8, near the outer edges thereof, and are guiiimed ontheir inner surfaces. It

will be seen that the inueilage for the said upper'and lower flaps isapplied between the score lines and the outer e( 'ges of said flaps. Itwill be readily understood that by score lines I mean the rines ofperforations vfhereby the marginal portions oi the said flaps can beleither surface thereof, comprising to UNITED srnins PATENT OFFICE; V

outer surfaces of the envelop as's'hown i'n Fig. 3. The first time theenvelollis u'sed the end flaps a are turned in, and t bottoni flaps arefolded over and secured in place, as shown in'Fig. 2. The receiver .ofthe envelop can then tear the top and bottom flaps along thescore lines,as shown in Fig.- 3,. leaving narrow strips adherin to the outersurfaces of the envelop. licse narrow csf strips can then be broken toerinit the end jf flaps a to be reversed or fo ded back and' broughtintothe positions shown iri Fig. 4,

bringing the gummed portions 1-2 and 3--4 into position toreceive 4themarginal portions of the said top and bottom flaps, as shown moreclearly 'in Fig. 4. When this is done the narrow adhering ortions of thefla s will be concealed within t ie envelop, and t e lat teris now readyfor use a second time. I n

this'way the envelop is readily rcversible'land.

need not be thrown uway'lwhen it is received for the first time. Thereturn card of ,the first. user can be rinted on the outside of theblank and the at dress of the first user can be printed on the insidethereof, if such is del' sired. The envelop shown is left blank, sof.

that the address andreturn'cardcan written thereon. In the manufactureof the blank, the same need not be turned over, as the gumming is all onthe 'same side thereof, and only one guinniing operation is necessaryfor cacht lank. What I claim as my invention is:"-

1. A reversib' be folded and 0umnied together to expose bottoin fia-pshaving detachable ad erin portions, adapting said flaps for reveisal, anend aps which always go inside of the top and bottom fla s. i

2. A reversib e envelop blank having end flaps guinmed on the innersurfaces thereof, top and bottom flaps guinined on the iin'er surfacesthereof, said top'and bottom aps beingscored parallel with and neartheir outer edges to provide each flap with a detachable adhesiveortion, the um or adhesive material on tiie end flaps )eing adapted toreceive the top and bottom flaps after the lat-ter are reduced bytearing them along their scei'c. lines.

- 3. A rcve'rjsible envelop blank having end 'ifoo ie envelop blankadapted to and surfaces thereof, apluialityofrsaid flaps be- 10 eitherdirection', the upper and lower a s having detachable adhesive ends 'toma e the envelop reversible. 5. A reversiblecnvelop blank A havin endaps afa., seid end -flaps being gunime 15 at 12 and 3--4 on the innersurfaces there: tof, top and bottom flaps al, a, said top ,and bottoniflaps bein?,` scored et 5--6 and 7 8,

near the outer edges thereof, to provide de.

tachsble end portions X and Y which go in- 20 side when the envelop isreversed, said topf and bottom flaps beinff guninied between the saidscore lines and their outer edges, substantislly as s'et forth.

6.- The improved reversible envelop, p'ro- -25 4vided with end flapspummed on the inside to receive the to `and bottom flaps when theenvelop is used t e second time, said top and bottom flaps havingdeteohablelapping end.
